There are certain pieces of equipment that you purchase that really are worth sharing. This piece of equipment falls into that category. The speaker box floats, is waterproof, and has storage for valuables (fishing license, keys, etc...) plus plays music at a pleasant volume and has long battery life. Check it out if you are in the market for a waterproof speaker for float trips.
So far, it has exceeded all expectations. One set of batteries covered a week on the Alagnak. Another set of batteries covered 11 days on the Kenai. Great product that I highly recommend.
